Holotype: No. In 45364 (reverse). Specimens No. In 45529 and 
In 45504 are apparently the same species. British Museum (N.H.), 
London. Collected in Upper Permian, Belmont, Australia (N.S.W.). 
Phyllelytron petalon, n. sp. 
Text-figure 2 
Fore wing: 19 mm. long, 6.5 broad; sutural margin considerably 
narrow; tubercles well developed on the whole posterior half of the 
wing; granulation medium coarse; costal expansion projecting, cir- 
cular; branches of R slightly oblique, irregular, connected with many 
cross veins; cross veins numerous, very irregular; veins and cross 
veins not pigmented, interspaces between them darkly pigmented 
before all in the distal half of the wing; darker spot before the mid- 
dle of the wing, along the basal part of the anterior margin and 
round the base. 
Relationship. Phyllelytron petalon, n. sp., is related to P. granu- 
latum, n. sp., by darkly colored tegmina with unpigmented veins. 
It differs from this species in its finer granulation, distinct tubercles 
and relatively large, different pattern of colored spots and irregular 
cross veins. 
Holotype: No. In 45703 (obverse). Specimens No. In 45528 
and 45734 are probably this species. British Museum (N.H.), Lon- 
don. Collected in Upper Permian, Belmont, N.S.W. 
Phyllelytron granulatum, n. sp. 
Text-figure 3 
Fore wing: 15.2 mm. long and 5.3 mm. broad; sutural margin 
narrow; tubercles indistinct; granulation coarse; costal expansion 
projecting; anterior margin strengthened, pigmented in the proximal 
half; branches of R indistinct, irregular, connected with cross veins; 
cross veins not very numerous, irregular; veins not pigmented, three 
dark colored spots in the proximal half of the wing. 
Relationship : Phyllelytron granulatum , n. sp., differs from all 
species of the same genus in smallest dimensions, coarsest granulation 
and indistinct tubercles. 
Llolotype: No. In 38113 (reverse). Specimens No. In 45513 and
